I have teams here that I've attended games for and followed nearly religiously since I was a child. I don't pay to watch them if they aren't putting a product out that I like. I try to be reasonable when I look at the outlooks of the teams I follow. Everton's squad is still a mid-table squad. I think we all knew that at the start of the season, or should have known that.
Eyes can deceive. Easily. Give your eyes some context to help.
Silva not being able to put a mid-table squad in the top 6 in one season isn't a concern to me. People look at the turnaround from people like Mourinho to Conte, winning the league a year after they finished whatever position. Everton's squad is not nearly at that level to allow such a turnaround. When Everton add players like Hazard, Kante, D. Costa, Azpil, Higuain, etc, then I'll expect results faster.
I get being frustrated with the situation that Everton have put themselves in over the past 4-5 season, but there are no miracle cures.
